This would be nice if it happened, but I give it 1% tops. Elon especially, the government has its fingers in his businesses and would likely step in to cut a deal even if his money couldn't save him. But since he didn't break any American laws and the 1st Amendment is a huge thing, I doubt he'd be extradited in the first place. He might in that case end up with a standing warrant that would get him arrested the minute he stepped foot over there, though, if he's tried in absentia.

I don't know anything about UK law so I have no idea what would happen to her royal terfness, but she's got dump trucks full of money, so she's probably fine. If there's one thing that's the same everywhere in the world, it's that rich people live by their own set of rules.
